I have a 2004 Prius and need a battery rebuild, I see where there are some battery cells being sold and listed as being for various years of gen 2 and gen 3 Prius. I have available a 2012 Prius C for a donor battery, (totaled, but still has the battery) So the question is are the cells or battery packs the same across the gen2 & gen 3 cars.?
I just found an informative thread on here for this topic.. Now my question would be how many cells are in a prius C battery pack?
20 modules in a C. Can't make any promise about how well it will work mixing Gen 2 and Gen 3, but I suspect there wont be any problems. I used 2 "C" batteries to do a complete module swap on a 2005 that my son is driving. The other 12 that were left over went to ebay.
Thanks a lot for clarifying that, I looked everywhere to try to find out how many cells were in a Prius c. I definitely did not want to mix gen 2 and gen 3 cells, I was attempting to find out how many more I needed of the gen 3 cells to make a whole set of 28 for my gen 2 Prius. Another thread mentions not to mix 2 & 3 cells because there is a diffence in them, not in fitting but in their resistance or something. I couldn't check the c battery until I get it to take it apart, which I was holding off on just to do the math to see how this would work out.
Have done this before with no dramas, low capacity will catch you out before resistance. Battery computer reads resistance in pairs/blocks just trick it by putting one module of each generation per each block/pair so the overall resistance for each block is similar throughout the 14 blocks good luck
